The Mondego, the largest river with a wholly Portuguese soul, offers a crossing here: a dam that serves as a natural bridge. Tread carefully, but don't forget to look up, because the view from the heart of the river is unique. The crossing is usually easy in any season, but if the rains are heavy, it's best to turn around and let the current take its course.
